Release Notes: This release operates over UDP rather than TCP. It can transparently operate through firewalls. The core architecture and algorithm have been redesigned for simplicity and efficiency. A new and even simpler API allowing the rapid development of third party software that interacts with Freenet has been added.

Release Notes: New features include NIO technology that brings
improved performance while using less CPU and
system resources. Individual nodes are now more
efficient, and the speed and routing of the entire
network were significantly improved.
Probabilistic caching was implemented, which
further improves routing and lets Freenet store
and find more data. Some user interface
improvements were made. More improvements were
made for downloads of large files. The Heisenbug
and tons of other bugs were fixed.

Release Notes: Very many changes, rewrites, and bugfixes were
made. Almost every part of the software has seen
dramatic improvements in speed, stability, and
security. This is the first stable release in over
14 months. Those familiar with previous releases
should be pleasantly surprised by its speed and
stability.

Release Notes: Yet more work to improve load-balancing, and the experimental introduction of initial first-step random routing, which should improve the network's ability to find even infrequently requested data.

Release Notes: There are a large number of fixes for serious bugs which were causing nodes in the network to become overloaded, dramatically reducing the usefulness of Freenet. These fixes have already caused a dramatic improvement in network performance. This release, once widely deployed will improve things further. The format for versions has changed: 0.4 is the major version, and 482 is the build number (this is incremented every time a significant non-cosmetic change is made). Upgrading is essential for anyone running a build older than 2 weeks (build 480).
